David Makin has put together a new post to his site showing you how to make a simple REST web service with Silex, the PHP microframework from the Symfony project.
So you have come to the conclusion that, rather than having the code to update customer details and that little fix to convert the date from GMT to UTC should happen in once place rather than being copied into several pieces of code, a REST service is the answer. Perhaps you just think you should know how to create a REST service. Either way this post is for you. In this post we will start off with a blank directory and go through installing Silex and getting it to serve a couple of simple routes.
He helps you get Silex installed via Composer and gets you started with a simple root and "stock code" route. He uses these to explain a bit about the framework's route handling and includes URLs to call that will execute them.
